Justin proposed to her on his birthday
on August 10, with a spokesperson for Theroux, the cousin of British
documentary-maker Louis Theroux, confirming at the time: 'Justin Theroux
had an amazing birthday on Friday, receiving an extraordinary gift when
his girlfriend, Jennifer Aniston, accepted his proposal of marriage.'

The wedding will be a second for Jennifer, whose marriage to Brad Pitt ended in 2005.

Since then she has dated a string of
men, including Vince Vaughan, Bradley Cooper, John Mayer and Owen
Wilson, but the relationships have all been short-lived.
